Tariff refunds have begun reaching U.S. companies after a Supreme Court ruling earlier this year found some tariffs unconstitutional.

Firms like Oshkosh Corporation and Basic Fun confirmed they have started receiving partial payments, though the total refund amounts are still being calculated.

Logistics companies such as UPS, FedEx, and DHL are helping process claims, which could ultimately total over $35 billion according to U.S. Customs and Border Protection estimates.

The refunds stem from a court decision invalidating tariffs imposed under emergency economic powers, prompting businesses to file claims through a federal system, CNBC has reported.

Former President Donald Trump criticized the refund process, calling it “crazy” and saying the government would fight the payouts.
